Description

Utilities for validating configuration values

Synopsis

Documentation

type ConfigValidation α λ = forall μ. (MonadIO μ, Functor μ, Applicative μ, MonadError Text μ, MonadWriter (λ Text) μ) => α -> μ () Source

A validation function. The type in the MonadWriter is excpected to be a Foldable structure for collecting warnings.
